Given point Y is between X and Z, where XY = 12 and XZ = 48, What is YZ?

Answer: 4x^4

Step-by-step explanation:

from the law of indices,

( a^x)^y = a^xy

Now from the question

( 8x^6)^2/3

8^2/3X^6x2/3

From another law of indices,

a^x/y = ( y cube root of a)^x

8^2/3 = 2^2 = 4 ——— 1

Now X^6*2/3

= X^4 ——————-2
Now combine 1 & 2 together gives the answer

= 4x^4

Answer: y = -4x + 13

Step-by-step explanation:

Given points (2, 5) and (3, 1)

First Step find the slope given the two points:

Use the slope formula [tex]m=\frac{y2 - y1}{x2 - x1}[/tex]

[tex]m = \frac{1-5}{3-2} = -4[/tex] (Result)

Slope is equal to -4

Second step plug into y - y1 = m(x - x1) formula (Point Slope Formula)

For this I am using the first coordinate pair given (2, 5)

y - 5 = -4(x-2)

y - 5 = -4x + 8

y = -4x + 13

By substitution, the solution of the system of equations, r + s = -12 and 4r - 6s = 12, is (-6 , -6).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in r and s,

r + s = -12     (equation 1)

4r - 6s = 12     (equation 2)

Using the first equation, find the value of one variable, lets say r, in terms of the other.

r + s = -12     (equation 1)

r = -12 - s

Substitute the value of r to the second equation.

4r - 6s = 12     (equation 2)

4(-12 - s) - 6s = 12

-48 - 4s - 6s = 12

Combining all terms containing the variable s on one side and the constants on the other side of the equality, and solving for s.

-48 - 4s - 6s = 12

-4s - 6s = 12 + 48

-10s = 60

s = -6

Substitute the value of s in the equation of r and solve for r.

r = -12 - s

r = -12 - (-6)

r = -12 + 6

r = -6

Hence, the solution of the given system of equations is (-6 , -6).

After a translation 4 units left, a reflection across the x-axis, and a translation 2 units down, the coordinates of the image are (-1, 2).

In mathematics, a translation is the movement of a shape to the left or right, and/or up or down. The translated shapes appear to be the same size as the original shape, implying that the shapes are congruent.

They have simply been moved in one or more directions. There is no change in the shape because it is simply moving from one location to another.

According to transformation rule in graph, when moving it to the right, you add the x value And when moving to the left, you subtract the x value,

Value of x = 3

Here the reflection of x has translated 4 units left, which implies

3 - 4 = -1

And, when moving up you add to the y value and when moving down you  subtract to the y value,

Value of y = 4

Here the reflection of y has translated 2 units down, which implies

4 - 2 = 2

Thus, the coordinates of the image formed by the reflection are (-1, 2)

On simplifying the expression 13.8+ (-11.5) , we get 2.3 . And additions

13.8 + (-11.5) and (-13.8) +  11.5 are numbers will same value and opposite sign.

For adding a negative and a positive number, use the sign of the larger number and subtract.

For example: (–8) + 2 = -6

Given that we have to solve 13.8 + (-11.5) = 13.8-11.5 (we subtract smaller no from larger and will use the sign of lager number that is + here)

13.8+(-11.5) = 13.8-11.5 =2.3

13.8+(-11.5) simply means that 13.8 -11.5 which is subtraction of 11.5 from 13.8

but (-13.8) +  11.5 = -13.8 +11.5  =  -( 13.8 -11.5) [taking -1  common from the expression]

The explicit formula for the given sequence is a(n) = 1 + 4(n - 1).

A recursive function is one that iterates or uses its very own previous term to determine subsequent terms, resulting in a series of terms.

The recursive formula for an arithmetic sequence is as follows.

a(1)  = 1 and a(n) = a(n - 1) + 4.

Remember that this formula provides us with two types of data.

Let's look for a formal formula again for sequence.

Answer:

Perimeter: 2(7+12), 2*7+2*12, 7+12+7+12

Area: 7*12, 7*10 + 7*2

neither: 7+12

Step-by-step explanation:

perimeter is like if you want a fence all the way around your property and your yard is 7x12 feet. In that case you could use the first option because you have to count the sides and add them up. If it’s a rectangle then there are 2 12’s and 2 7’s so the first one would work. The fourth one also uses distribution. The Fourth and first one are pretty much the same and have the same answer so the fourth one would work for perimeter.

Another way to do perimeter is to instead of multiplying, is to add the sides. 7+12+7+12 is basically 7 times 2 plus 12 times 2 (the fourth ne) and the answer is still correct so this one works too,

For area you times one of the dimensions by the other so 7*12 would work for area.
7*10 + 7*2 would also work because that uses the distributive property and that’s 70 + 14 which is 84 which is still the same answer.


The only one that falls under neither is the fifth one. 7+12 is half of the perimeter because it only adds two of the sides together and has n multiplying so it’s not area either.

The expression "quantity negative three and one third times n plus one sixth end quantity plus quantity one and three sixths times n minus three twelfths end quantity" or (-3 1/3n + 1/6) + (1 3/6n - 3/12) is equivalent to "negative eleven sixths times n minus one twelfth" or -11/6n - 1/12.

An algebraic expression is a number, variable, or the combination of both and operational symbols.

To determine the equivalent of the expression "quantity negative three and one third times n plus one sixth end quantity plus quantity one and three sixths times n minus three twelfths end quantity" or simply (-3 1/3n + 1/6) + (1 3/6n - 3/12), combine all like terms and perform necessary operations.

(-3 1/3n + 1/6) + (1 3/6n - 3/12)

⇒ -3 1/3n + 1 3/6n + 1/6 - 3/12

⇒ (-3 1/3 + 1 3/6)n + 1/6 - 3/12

⇒ (-10/3 + 9/6)n + 2/12 - 3/12

⇒ (-20/6 + 9/6)n - 1/12

⇒ -11/6n - 1/12

Answer: C. 7/9

Step-by-step explanation:

An arithmetic progression (AP) is a sequence of numbers ordered such that the difference between any two consecutive numbers is a constant value. Also called arithmetic sequence. For example, the sequence of natural numbers: 1, 2, 3, 4, 5, 6, … is an arithmetic sequence in which the common difference between two consecutive terms (e.g., 1 and 2) is 1 (2 - 1) ... It can be seen that the tolerance of two consecutive terms is equal to 2, even for odd and even numbers.

First term a=-3.5,

Common difference d=2.25,

Number of terms n=8

Solution:

Here first term a=-3.5,

Common difference d=2.25

We know that,

f(n)=a+(n-1) d

f (8)=-3.5+(8-1)(2.25)

=-3.5+(15.75)

=12.25

We know that,

Sn=n2[2a+(n-1)d]

∴S8=82⋅[2(-3.5)+(8-1)(2.25)]

=4⋅[-7+(15.75)]

=4⋅[8.75]

=35

Hence, 8th term of the given series is 12.25 and sum of first 8th term is 35.

Independent events are those where the occurrence is unrelated to any other event.

Now, as for the given question.

There are two events given as A and B.

The probability of occurrence of event A is P(A).

The probability of occurrence of event B is P(B).

The occurrence of the event A when B is already happened is denoted by P(A | B).

The intersection of events A and B are given as; P(B ∩ A).

Now, it is given in the question that;

P(A | B) = P(A) and P(B ∩ A) = P(B)

P(A | B) = P(B ∩ A)/P(B)

This can also be written as;

P(B ∩ A) = P(A | B).P(B)

Now, P(A | B) = P(A), replace in the obtained equation.
